High Performance Pneumatic Triple Offset Wafer Butterfly Valve

High Performance Pneumatic Triple Offset Wafer Butterfly Valve

OVERVIEW

This pneumatic stainless steel wafer butterfly valve consists of a pneumatic actuator and butterfly valve body. It adopts wafer mounting design with compact structure and light weight. Driven by compressed air, the valve disc rotates 90° to realize quick on-off or flow regulation of pipeline media.Main pressure-containing parts are made of stainless steel for outstanding corrosion resistance. The metal hard-sealed version can withstand high temperature and high pressure service conditions. It delivers reliable sealing performance, low flow resistance and simple installation & maintenance. Widely used in petroleum, chemical industry, power plant, metallurgy, water treatment and other sectors for cut-off and throttling of gas, liquid and partial steam media.Optional accessories: valve positioner, limit switch, solenoid valve and handwheel override mechanism to meet automatic control and on-site emergency operation requirements.

FEATURES OF ELECTRIC ACTUATORS

PRODUCT ADVANTAGES

Diversified needs

The process technology sites of supporting pipelines and automated valves are all over the world. Not only the site and valve type are important factors in the selection of electric actuators, but also the climate environment of on-site operation is crucial. FRY-A electric actuators guarantee safe and reliable service under various extreme environmental conditions.

Superior performance

Quality Assurance

Only when all on-site equipment provides reliable service throughout its entire life can the entire process site be efficient, economical and safe.

Long warranty period

MAIN FUNCTIONS

Explosion Proof

Based on your specific hazardous area classification and medium type (Group IIA/IIB/IIC gases or dusts), custom-engineer explosion-proof mini‑type electric flanged ball valve consists of an electric actuatorthat fully comply with international and domestic standards, including IECEx, ATEX, and GB 3836.

Colors

You can provide your own color code or choose special coatings for corrosion resistance, weather resistance, or high-temperature warning. Using advanced spraying technology and high-quality coatings, we ensure a durable, uniform finish. This gives your equipment a personalized look while maintaining long-term durability in industrial environments.

Protection grade

Based on your installation environment - outdoor rain, coastal salt spray, desert dust, or food/pharma workshops needing high-pressure washing. We provide sealing solutions from basic dust/water protection (IP65/IP67) to ultra-high protection (IP68/IP69K).

Low-temperature

For the specific operating conditions in extremely cold regions, we offer professional, deeply customized low-temperature environment services for Manual Worm‑gear PTFE‑Lined Butterfly Valve . By employing special low-temperature resistant materials, wide-temperature-range lubricants, and intelligent heat tracing systems, we ensure that the equipment can reliably start and operate accurately even in extremely low-temperature environments. We also comprehensively optimize the cold resistance of seals, electronic components, and display screens to effectively prevent problems such as lubrication freezing, sluggish displays, or start-up failures caused by low temperatures.

CONTROL MODE

External control All actuator signals, such as limit switch signals, torque switch signals, motor thermal protection and valve position, can be transmitted to the external control device for further processing. When designing the control logic architecture, it is necessary to fully consider the necessary protection mechanisms and minimize the delay time.

The contactor device used to control the operation of the motor is installed in the external control device and connected to the actuator via a cable.

When a local control operation interface is required, the local control operation interface should be installed near the actuator and integrated with the external control device.

Integrated control

When the actuator is powered on, the actuator with integrated control unit can be operated by the operating elements of the local control. The control unit is fully adapted to the actuator. The actuator can be set up on site without connecting to the DCS system. Only the transmission and exchange of operating commands and feedback signals are required between the control system and the actuator. The on-off control of the motor is completed instantly in the device.

Fieldbus

The use of bus cables can save a lot of space in the control cabinet, and it is more obvious that the traditional input and output signal line connection is outdated. The use of two-core cables simplifies the commissioning phase and greatly reduces the cost of cables in the long-distance field.

Another major advantage of fieldbus technology is the transmission of preventive maintenance and diagnostic information to the control room. Therefore, fieldbus technology integrates all fieldbus devices into the asset management system to support the safety protection measures of field device utilization. Actuators equipped with intelligent integrated control units can be applied to various common standard types of fieldbus systems in process automation.
